![]() Types of Allergic Diseases Common allergic diseases include eczema, hives, hay fever, asthma, food allergies, and reactions to the venom of stinging insects such as wasps and bees. Some of the allergic diseases are discussed below; • Allergic Rhinitis: Allergic rhinitis is the most common allergy diseases which are defined as inflammation of the nasal membranes.

The skin of a patient with atopic dermatitis reacts abnormally and easily to irritants, food and environmental allergens and becomes red, flaky and very itchy. It also becomes susceptible to surface infections caused by bacteria. • Urticaria: Urticaria, also known as 'Hives' are a kind of allergic disease or skin rash notable for dark red, raised and itchy bumps. It can be triggered by many substances or situations and usually starts as an itchy patch of skin that turns into swollen red welts. The itching may be mild to severe. Scratching, alcoholic beverages and emotional stress may worsen the itching. Treatment of Allergic Diseases A variety of tests now exist to diagnose allergic diseases; these include testing the skin for responses to known allergens or analysing the blood for the presence and levels of allergen-specific IgE. Treatments for allergic diseases include allergen avoidance, use of anti-histamines, steroids or other oral medications, immunotherapy to desensitise the response to allergen, and targeted therapy of allergic diseases. |
